- METALLIC CAP FOR BECEPTACLES AND METHOD OF MAKING THE SAME To all whom it may concern:

Be it known that l, W LLIAM H. Donsn, a

citizen of the United States, residing at Ve- -rona, in'the county'oi Essex, State of New Jersey, have made a certain new and useful Invention 1n Metallic Caps for Receptacles and Methods of Makin the Same, of which the following is a s iccilication.

'lh1s invention re ates to metallic or other caps or clhsures for receptacles and method of making the same.

- The object of the invention is to provide a metallic or other cap for use on receptacles, and particularly designed for use on receptacles containing carbonated gaseous li'quids, such as beer or the like.

Another object of the invention is to pro-.

views, Fig. 9, being in section showing other forms of embodiments 01'' caps or closures in accordance with my invention. Fig. 11, is a broken detail view in section on the line 11,11,Fig..3.

The same part is designated by the same reference sign wherever it occurs throughout the several views.

' In the manufacture of caps or closures for receptacles such as bottles, jars, cans or the like, it is exceedingly desirable to produce a device which is not only simple in construction. and economical to manufacture, but

also which is capable of being readily, easily and quickly ap lied to or removed from the receptacle, whie at-the. same time ellicientin hermetically sealing a receptacle when-applied thereto. This 15 a specially; desirab e object to' attain in closures employed for receptacles adapted to contain carbonated or char ed liquids, such, for instance, as beer bott es or the like. I

In attaining simplicity of structure it is desirable to avoid employing a plurality of arts; in attaining economy in manufacture it is desirable to avoid the necessity for assembling the parts by hand; in attaining elliciency, ra idity and ease in the a plication of the OliJSUIQ' to, or its removal rom a receptacle, it is desirable to provide means whereby the effective inclosing or surrounding diameter of the closure may be contractible, and in the case of closures for useon receptacles containing carbonated or charged liquids, it is desirable to provide means whereby the closure can withstand ethciently, Without permitting leakage, the pressure of the gas or other charging agent contained within the rece .tacle.

It is among the specia objects and purposes of my present lnvention to accomplish these various purposes, and to attain the results stated in connection with closures specially designed for use on rece tacles containing carbonated or charged iquids, and

in carryin out my invention I propose to form thee osure from a single piece of material, preferably sheet metal, as tin, although I do not desire to be limited or restricted in this regard.

In practice, I propose to produce from a sheet or plate of the selected metal or material a portion. of sutlicient size, and of the desired contour to form a blank from which the closure by suitable and proper manipulation out.

is formed. From tins piece of .niat-eriol ablank for the closure produced by suitable stamping, dr" i or otherwise forming the same into substantially the shape of a cup, in preliminary stage of production. of the closure. ll is obvious um the plate may rhereby provided with a top or erb'wn pori ion 12, with :1. dependent inregral continuous i lhuige 13. in drawing, stamping or e therwise forming lhe blank into cup shape, 1 prefor to nnzlie the same, or the top or crown porlion 12, thereof, of oval shape, as clearly shown in Fig. i, that is, into such shape that the dianieler in one direction is longer than the diameter in ihe other direction. The next slop in the operaiion to form a slir or oui H, through the lop or erown portion 12, see Fig. i!) remove a, narrow crescent shaped slrip lherclroin leaving the space ll. "l space, as shown in Fig. 2, extends in a line adjacent iihe peripheral edge of the blank, bui sulliciently removed from such edge to leave a portion l5, oi the top or crown connected lo umporiiion of the llsn-ge l3, whioh by the slifor cut 14, is separated from the remaining portion of the blank, as clearly shown in the drawing. li'e'hn'ably, the slit or out ii, extends aboufi a seini-circuinl'erence ol' the blank and at the ends thereof said slitv or out approaches more closely the peripheral edge of the blank than at points intermediate such ends, there- I by gradually dcereasing the Width or extent of the'lip 15, rewards the ends of such slit or The slit or cut may be continued beyond the termination of the lip or llunge l5, and in line with the inner surface oi the flange 13, as clearly indicated at 16, Fig. 2, thereby providing a short sectioirnf flange 19, which ciiher with or Without beingredueed in width, may be folded into a loop 17, in order lo coulrael; the effeetive inelosing diameter of such llzinge, and if desired, in order to a'll'ord means for readily releasing I i the closure when ihrsame is m be removed from the receptacle, one of the folds of loop l7, may depend below the edges of the other folds, as indicaied at 42, Figs 8 and ll in figs. 6, and l have shown a slightly niodilied arrangement wherein the 'l oldable or loop portions i3, are i'ornied at each end ol' Lho still or cul H, said cut being extended beyond lerinii als ol' the lip' lS, as indicated at 32 ll obvious'that other modiiiealions and varial ions to the number or location oi lhe {-Illlliblfi portions may be cinbodied withou i departure from the spirit or scope of my invention. 1 do not desire,

the

therefore, to be limited or restricted in these respects. After the cut or slit ll, has been made in the blank, as above described, the next step in the operation is lo reduce the top or crown portion to circular shape or contour. This, in accordance with the principles of my invention, is accomplished by bending down, at substantially right angles with reference to the plane of the top or crown portion 12, rhe bounding edge of the slit or cut ly-l. l have shown in dotted lines at 20, i'he line ol' bend of that portion oi the top or crown. which forms the bounding edge of {he slit or out 14. lb will be seen that the 'porrion or ihinge thus bent down from the edge of 'the slit or cut is of crcsceni shape, being widest at a point midway between ihe ends thereof,

and layering from such niid doint towards the on s thereof, as clearly indicated 'lliis edge or lip thus hen'tv down is indicated most clearly at 21, in Figs. 5, 8, 9 and i0, and i'ornis a reinforcing lip or ilango for that portion of the flange 13, which has been parliolly separated by the cut or slit H. The next slop in the operation of nnnnil'acture of my improved closure for receptacles coniaining carbonated or charged liquids is to contract the eli'ective inclos'ing diameter oi" the llnnge 13. This is accomplished by l orniing the loop or fold l7, l8, therein, as above lihl'ltioncd, thereby drawing the separated portion of the flange into eorrespoinlence with the circular contour of ihe crown portion, to which condition such crown porrion has been reduced by bending down so "pleinentary lip or llunge 21. in other worr s, when the lip 21, is bent down, as above described, the crown portion of the closure is not only thereby reduced to substantially circular contour, but is reduced to a smaller diameter than the diameter of lhe flange, and therefore, by forming the loop or iold l7, 8, the diameter of the flange is correspondingly contracted, and in thuscontracting the flange L arrange the lip 15,-lhereon to engage over the edge of the crown portion formed bybending down the auxiliary lip or flange. 21 clearly shown in Figs. 5, 8, 9, and 1t).

From the foregoing description it will be seen that the closure is reinforced by ihe. auxiliary lip or flange ll, along that part thereof \vl'iere reinforcement is most necessary, namely, along the line of the slit or cut l l.

In practice, This auxiliary lip or flange is coin- ,7

'parai ively short in Widih as compared with vthe width oi" flange 13. adjacent thereto, -and venting any esca e or leakage even under thetension of a high pressure carbonic or charged liquid or other content of the receptacle and enabling the ca to form a temporary cover for the receptac e even after the detached portion of the flange has been broken off and thrown away. In practice, and if desired, though to this my invention is not to be limited or restricted, the flange 13, may be reduced in transverse width, as indicated at26, Fig. 8, in order to enable the fold 17, to be formed therein with facility, and in order to enable the bend or fold of the flange to be loosened whenever it is desired toreniove the closure'from the receptacle. The provision of this auxiliary lip also prevents the pressure of gas in the rece tacle from being exerted against the detac 16(l portion of the flange thereby tending to cause the same to open up and which would result in leakage.

If desired the cap may be concentricall r scored or grooved, as indicated at 10, which serves as a strengthening and bracing means for the material of the cap andhence permitting the use of thinner andlighter mate-- rial.

A closure embodying the principles of my invention as above described, ma be applied to a receptacle or to the mouth or neck of a bottle, can, jar or the like, in any suitable or convenient manner. Ordinarily, the

lower edge of the flange 13, is crimped or:

bent underneath a shoulder 27, formed on or adjacent the mouth of the receptacle. If desired, the closure may be provided with a disk or washer of suitable packing material, indicated at 28, Fig. 8, and which is designed to rest upon the end surface of the-rece tacle being pressed. there against by t 1e bottom surface of. the closure. If desired, the edge of the )acking disk or washer may extend beyond t he edge of the mouth of the receptacle, and down the exterior surface or sidethereof, as indicated at 29, Fig. 8.

In Fi 9, I have shown a slightly modified form' 0 closure embodying my invention,

wherein the central )art 30, of the cap or closure, is depressed below the plane of the outer or bounding edge thereof, thereby forming a )eripheralchannel or groove which receives the edge ofthe receptacle mouth. In this channel or groove, if desired, may be laced'a packing ring or washer 31. In this orm of cap or closure and application thereof, the depressed central portion 30, aids in resisting any tendency to leak, while the channel and packing ring or gasket 31, therein, increases the resistance to leakage. This form of cap I have found effective and par ticularly desirable, though it is to be distinctly understood that my invention is not to be limited or restricted in these respects.

In Fig. 10, I have shown another somewhat modified arrangement wherein, instead of depressing the central portion. of the cap,

carbonated or charged contents.

Having now set forth the object and nature of my invention and various constructions embodying the principles thereof, I desire to be understood that many variations and changes in the details of construction and arrangement might readily occur to persons skilled in the art and still fall within the spirit and scope of my invention,but
